The major forces driving farm-level production for the ever-growing global population have relied upon mechanized farming techniques, synthetic inputs, and developing high-yielding crop varieties. Recently, however, there has been a gradual shift toward sustainable approaches addressing potential use of beneficial traits soil-plant microbiome to establish food supply as well maintain soil plant health. intricate relationship complex often faces difficulty in efficient translation broad...
Boxwood, valued at over $140.9 million annually in the United States, faces a significant threat from boxwood blight disease. This study evaluated 24 treatment combinations involving three fungicides (Daconil Weatherstik, Postiva, and F6123-1), disinfectant/fungicide (KleenGrow), host-plant defense inducer (Actigard), an anti-transpirant (Vapor Gard) for managing blight. Preventive applications were performed h before pathogen inoculation, while curative treatments applied 14-d intervals,...
Studies have shown the potential of rhizobia and associated micronutrients to enhance symbiotic nitrogen fixation in legumes. Tens millions smallholder farmers, however, farm on mountain hillsides highly variable soil microenvironments, with different crop rotations, inputs cultural practices. Here, terraces Nepalese Himalayas, we evaluated rhizobium inoculants (local, exotic), (molybdenum, boron) their combinations as technologies for farmers under microenvironments traditional The study...
Phytopythium vexans and helicoides are important waterborne plant pathogens causing root crown rot disease in plants from different families ( P. = 19 18) worldwide. The main objective of this diagnostic guide is to provide detailed information about symptoms signs disease, host range, geographic distribution, pathogen isolation, conventional molecular identification, storage, pathogenicity testing, present a reliable zoospore production procedure for these pathogens. This aimed at...
Plasma-activated water (PAW) exhibits potent antimicrobial properties attributed to the generation of diverse reactive oxygen and nitrogen species. This study assessed effectiveness PAW in vitro against phytopathogenic
Boxwood is one of the most popular evergreen shrubs in United States, production which currently challenged by boxwood blight, an emerging threat that has spread across 30 states. A thorough understanding production, plant health, management practices and economic impact could aid answering needs nursery industry managing this disease. An online modified Delphi survey was conducted to identify grower perceptions on processes, programs, limit or prevent entry blight The expert panel consisted...
Abstract Phytopythium vexans is an emerging phytopathogenic oomycete reported to be causing diseases in plants from multiple genera and families. It a soil water-inhabiting with sexual asexual life cycles present the environment. Sexual stages produce oospores whereas zoospores. This pathogen has been infecting crops Africa, Asia, Europe, North America, Oceania, South America. Mainly root crown regions of numerous perennial woody plants, herbaceous weedy annual cereal crops, forest...
Abstract Boxwood (Buxus spp.) is the most commonly cultivated woody ornamental shrubs in landscape settings and nursery production. grown for its attractive evergreen foliage versatility both formal informal gardens. Meeting high demand boxwood plants worldwide has become challenging recent years as industry been negatively impacted by a growing number of serious diseases arthropod pests. Globally, common arthropods concern are leafminer (Monarthropalpus flavus, Diptera: Cecidomyiidae),...
Phytophthora root rot, caused by cinnamomi Rands, is one of the major diseases flowering dogwood (Cornus florida L.). The severity rot disease increases when plants are exposed to flooding conditions. A study was conducted determine efficacy and timing application different fungicides, biofungicides, host-plant defense inducers, fertilizer manage in month-old seedlings simulated events for 1, 3, 7 days. Preventative treatments were drench applied 3 weeks 1 week before whereas curative 24 h...
Calonectria pseudonaviculata, responsible for boxwood blight, produces sticky conidia that pose a contamination risk in production via cross-contamination from tools, equipment, and other resources. This study evaluated UV-C light-emitting-diode (LED) irradiation (263 to 287 nm) as disinfection method by examining its effectiveness inactivating determining the sensitivity. Conidial suspensions were exposed quantifiable doses under dynamic stirring condition. Average volumetric intensity was...

Phytopythium vexans (de Bary) Abad, de Cock, Bala, Robideau, A. M. Lodhi & Levesque is an important waterborne and soil-inhabiting oomycete pathogen causing root crown rot of various plants including certain woody ornamentals, fruit, forest trees. Early accurate detection in the nursery production system critical, as this quickly transported to neighboring healthy through irrigation system. Conventional methods for are tedious, frequently inconclusive, costly. Hence, a specific,...
The use of untreated, recirculated irrigation water is a profitable practice, but it can harbor plant pathogens such as Phytophthora ( Pt) cinnamomi, Pt. nicotianae, Phytopythium Pp) vexans, and Pp. helicoides, posing disease risks in crop production. UV-C (240 to 290 nm) light-emitting diode (LED) irradiation was evaluated for inactivating the zoospores oomycetes water, providing potential effective treatment. Zoospore suspensions were exposed quantifiable doses under dynamic stirring,...
